Tapered vs. Uniform Tube-Load Modeling of Blood Pressure Wave Propagation in Human Aorta

Influence of flow and pressure on wave propagation in the canine aorta.

Adaptive Wave Propagation Modeling

This paper discusses several current attempts to use acoustic and electromagnetic wave propagation for modeling physical phenomena and the role that wavelet analysis is playing in these eeorts. The rst problem involves recent application of wavelets to computational uid dynamics. The second problem involves geophysical modeling of the ocean oor, using acoustic waves, and wavelets have recently ...

effects of two dimention external magnetic field on propagation of electromagnetic wave in uniform magnetized plasma slabبررسی اثرات میدان مغناطیسی خارجی دو بعدی روی انتشار موج الکترومغناطیسی در محیط پلاسمایی یکنواخت

جذب و عبور و بازتاب امواج الکترومغناطیسی در پلاسما موضوع مهمی است که مدت زمان طولانی مورد مطالعه قرارگرفته است. تحقیق بروی پلاسمابا توجه به کاربردهایی نظیر تولید انرژی ، عدسی پلاسمایی برای کانونش انرژی و ... از یک اهمیت زیادی برخوردار است. اغلب گفته میشود که 99% ماده موجود در طبیعت در حالت پلاسماست، یعنی به شکل گاز الکتریسته داری که اتمهایش به یونهای مثبت و الکترون منفی تجزیه شده باشد. این تخمی...

Finite Element Modeling of the Pulse Wave propagation in the aorta for simulation of the Pulse Wave Imaging (PWI) method

A large number of pathological conditions result in significant changes of the mechanical properties of the aortic wall. Using the Pulse Wave Velocity (PWV) as an indicator of aortic stiffness has been proposed for several decades. Pulse Wave Imaging (PWI) is an ultrasonography-based imaging method that has been developed to map and quantify the pulse wave (PW) propagation along the abdominal a...

Numerical Solution of Seismic Wave Propagation Equation in Uniform Soil on Bed Rock with Weighted Residual Method

To evaluate the earth seismic response due to earthquake effects, ground response analyses are used to predict ground surface motions for development of design response spectra, to compute dynamic stresses and strains for evaluation of liquefaction hazards, and to determine the earthquake induced forces that can lead to instability of earth and earth-retaining structures. Most of the analytical...
